Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing Marinelli beaker correction containers fail to effectively seal the gap between the high purity germanium gamma spectroscopy system and the detector, leading to instability in sample mounting, reduced reliability of detected values, and increased uncertainty in radionuclide analysis due to diameter mismatches.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a Marinelli beaker with a common diameter is used, then it can be universally applied to various detectors, but a gap is formed between the detector and the beaker contact surface, increasing geometric uncertainty
Solution Approach 1:
The patent introduces a correction container as an intermediary component between the Marinelli beaker and the detector. This correction container has a first contact surface that interfaces with the beaker and a second contact surface that interfaces with the detector, effectively mediating the diameter mismatch and eliminating the gap that causes geometric uncertainty while preserving universal applicability.
Solution Approach 2:
The mounting system is segmented into three distinct components: the Marinelli beaker, the correction container, and the detector. This segmentation allows each component to maintain its own dimensions and characteristics while the correction container serves as a customizable interface that adapts to different detector sizes, resolving the contradiction between universality and precision.
2Adaptability or versatility
If the Marinelli beaker contact surface diameter does not match the detector diameter, then various detectors can be used with a common beaker, but the sample position becomes unstable, reducing reliability of detected values
Solution Approach 1:
The correction container acts as a mediator that ensures stable sample mounting while maintaining compatibility with various detectors. It provides a precise mechanical interface that eliminates gaps and stabilizes the sample position relative to the detector, thereby improving reliability without sacrificing adaptability.
3Manufacturing precision
If a correction container is introduced to seal the gap, then geometric uncertainty is reduced, but the mounting and dismounting process becomes more complex
Solution Approach 1:
While introducing an additional component (correction container), the patent segments the mounting system into modular units with simple, standardized interfaces. Each component retains a straightforward structure, and the overall complexity is managed through modular design rather than complicating individual components.
Solution Approach 2:
The correction container is designed with universal applicability, serving multiple functions: sealing the gap, stabilizing the sample position, and providing a mechanical interface between the beaker and detector. This multi-functionality justifies the added component by consolidating multiple requirements into a single element, thereby limiting the increase in overall system complexity.
4Reliability
If the contact surface area between the beaker and detector is increased, then stability is improved, but the diameter of the beaker must be customized for each detector, reducing versatility
Solution Approach 1:
The correction container serves as an intermediary that enables a large contact surface area for stability while preserving the use of a common Marinelli beaker diameter. The correction container's first contact surface matches the standard beaker diameter, and its second contact surface matches the specific detector diameter, thereby achieving both stability and universality.
Solution Approach 2:
The contact interface is segmented into two separate interfaces: one between the beaker and correction container, and another between the correction container and detector. This segmentation allows each interface to be optimized independently - the first interface maintains standard dimensions for universality, while the second interface provides customized contact area for stability.
